DECLARATION

This user manual is an integrated user manual of the E70.D4S series piezoelectric controller. Please read this user manual carefully before using this controller. Follow the instructions in the manual during use. If there is any problem, please contact us for technical support. If you do not follow this manual or disassemble and modify the product yourself, the company will not be liable for any consequences arising therefrom. Please read the following to avoid personal injury and to prevent damage to this product or any other product connected to it. In order to avoid possible hazards, this product can only be used within the specified range.

Notice!
Do not touch any exposed ends of the product and its accessories. There is a high voltage inside. Do not open the case without permission. Do not connect or disconnect input, output, or sensor cables with power on. Please keep the surface of E70.D4S clean and dry, don’t operate in a humid or static environment. After use, the output voltage should be cleared to zero before turning off the controller switch, such as switching the servo state to the open-loop state.

Danger!
The piezoelectric power amplifier described in this manual is a high- voltage device capable of outputting high currents, which can cause serious or even fatal damage if not used properly. It is strongly recommended that you do not touch any parts that connect to the high-voltage output. Special Note: If you connect it with other products in addition to our company, please follow the general accident prevention procedures. Operating high-voltage amplification requires training professional operators.

Warning!
If the voltage exceeds the PZT’s tolerable range, it will cause permanent damage to the PZT. Before adding voltage to the PZT poles, it must be ensured that the positive and negative poles of the PZT are connected correctly and the operating voltage is within the allowable range of this PZT.

Cautious!
E70.D4S housing should be installed on a horizontal surface in an area with a 3CM air flow area to prevent internal convection in the vertical direction. Insufficient airflow can cause equipment to overheat or premature instrument damage.

Installation Precautions
Note! Improper installation of the E70.D4S piezoelectric controller may cause personal injury or damage to the E70.D4S piezoelectric controller! Installation and use of E70.D4S should be close to the power source so that the power plug can be easily and quickly disconnected from the main power source. Use included power cord to connect the E70.D4S piezoelectric controller system. If the power cord provided by our company must be replaced, please use a power cord with a large enough size and effective grounding.

Ensure ventilation
Note! Overheating of equipment due to high temperature may damage the E70.D4S controller!

• Ensure that the cooling area of the controller is sufficiently cooled.
• Ensure that there is adequate ventilation equipment.
• Keep ambient temperature to a non-critical level(<50℃ ).
• The temperature of cooling surface of the controller is>50 ℃, it is recommended to take external heat dissipation measures to improve the stability of the controller.

Connect power
Use the power adapter (output range +20V~+30V/3A) to connect to the power supply interface of the E70.D4S power supply.

Cable connection
When the power supply is disconnected, connect the PZT&Sensor cable to the E70. D4S controller interface. Note that the number on the piezoelectric actuator corresponds to the number of the controller. In analog control mode, when the signal source (signal generator, analog signal source, DA control card) output is 0, connect the SMB cable to the SMB interface of the E70.D4S controller. Connect to the computer control mode of the PC, connect to the PC through the cable connection USB interface or RS-232/422 interface socket.

Maintenance, storage, transportation

Cleaning measures
Note! The PCB board of the function module in the E07.D4S system is an ESD (electrostatic discharge) sensitive device. Take precautions against any static build-up of these devices before use to avoid contact with circuit component leads and PCB wiring. Before touching any electronic components, the body first touches the grounding conductor to discharge static electricity, ensuring that any type of conductive particles (metal, dust or debris, pencil lead, screws) enter the device. Be careful not to drop the equipment when cleaning, to avoid any form of mechanical shock! Disconnect the power plug of the E07.D4S system before cleaning. Prevent cleaning fluid and any liquid from entering the system module to avoid short circuits. For the surface of the system chassis and the front panel of the module, please do not use an organic solvent for surface wiping.
